The solution to the died training-No return

[Seager1989]

Hi everyone,

I am runing the hyperparameters tuning by mlrMBO, but some of the evaluation in an optimization process may have no return (mentioned in #38 FE3)), which will block the progress of the tuning. Is there a method in mlr or mlrMBO to kill an evaluation with NA return if it has been running for a long time?

Thank you!

mlrMBO has mechanism to terminate a process.If you use mlrMBO with mlr::tuneMBO you would have to solve that within mlr. If you use your own objective function with mbo() you can wrap this objective yourself with a function that handles the timeout.

As we won't introduce new features in mlrMBO, I close this issue. Be aware that in mlr3 this will be possible: mlr-org/mlr3#542
